Disposable irrigator drain with stoma cone for ostomy patients

ABSTRACT

This invention is for an irrigator drain for ostomy patients, particularly for irrigating into the stomas of colostomy patients. It is characterized by the provision of a stoma cone fixed to the outer or rear wall of a drain tube whereby to facilitate the application of the irrigator into the stoma; also to features of novelty and improvement which make the irrigator low in cost of manufacture and economical for disposal after a single use.

Heretofore, various devices and appliances have been used for irrigatingpurposes, including my inventions desclosed in U.S. Pat. Nos. 2,928,393,3,292,625, and 3,672,370. Also in the prior art is an irrigator having astoma cone which said cone is advertised to sell about 4.00 dollars to5.00 dollars. These I consider to be relatively high cost and alsoobjectionable because they are designed to be re-used and must be washedand sterilized after each use.

Another object of my invention is, therefore, to provide an irrigatorunit of such new and improved construction it can be manufactured andsold below the cost of present irrigators.

Another object is to provide a new and improved irrigator of such lowcost as to make it disposable after each use, thereby not onlybenefiting the patient but being most helpful to hospitals andinstitutions which handle irrigators and are happy to dispose of theseirrigators as well as other appliances and equipment adapted fordisposal.

Other objects and advantages of my invention will be appreciated bythose skilled in this art as the invention becomes better understood byreference to the followin g description when considered in connectionwith the accompanying drawings, in which FIG. 1 illustrates the usualmethod used by a colostomy patient to irrigate the bowel;

FIG. 3 is a front view of an irrigator drain illustrating an assembly ofparts which comprise a disposable irrigator of my invention;

FIG. 4 is a vertical section taken on the section line 44 of FIG. 3; and

FIG. 5 is a diagramatic view illustrating an assembly of parts in theuse of my invention as applied to a patient.

It will be understood that these drawings are diagramatic as to sizesand shapes for the purpose of illustrating the principles of myinvention.

wall 9. When the drain tube is a polyethylene material it is preferredto also make the stoma cone of the same or similar material so that thecone may be united entirely around its rim 14 to the film byconventional heat sealing, thus fixedly connecting the stoma cone to thedrain tube. When the stoma cone is located inside the drain tube asshown in the drawings a small slit 16 is made in the rear wall centrallywithin the rim 14 of the cone. The catheter 15 is pushed through thisslit opening and also through the tightly fitting opening 19 at thepoint of the cone and into the stoma as shown in FIG. 5. The catheterconnects with a tube 17 to an enema bag 18 or any suitable source ofwater supply. In actual practice the cone is inserted into the open endof the stoma and spreads the stoma sufficiently to make a water-tightconnection without harm to the stoma, as illustrated diagramatically inFIG. 5. The catheter 15 is carefully pushed into the stoma a suitabledistance as is well known in this art.

With my invention the stoma cone can be easily inserted into the'stoma13 by reason of the fact that the rim 14 of the cone serves as arelatively wide hand grip which may be easily manipulated. The rim 14also prevents the cone being inserted farther than necessary into thestoma.

It is preferred to hold the drain tube in position on the abdomen 19 ofthe patient by the use of a low cost belt such as 20, of heat fusiblematerial as in my U.S. Pat. No. 3,695,268 with the ends 21 of the beltheat sealed to the gasket and also to the drain tube if desired. Also asshown in FIG. 4, I provide a short elastic piece 22 for tension at oneend of the belt and cinch Referring more particularly to the drawings,my invention is characterized by the provision of a stoma conedesignated generally by 6 preferably disposed inside the drain tubewhich is designated generally by the reference numeral 7 and having whatI term front and rear sides or film walls 8 and 9, respectively. Thedrain tube may be of any low cost material and preferably 1 use a thinpolyethylene film suitable for heat sealing to other components of theirrigator, as will be presently noted. The bottom end of the drain tubeis open as at 10 so that the discharge falls into the commode or otherreceptacle. The drain tube has a stoma-receiving opening in its frontside near the top surrounded by .a gasket 11 having a relatively largecentral opening 12 registering with the stoma-receiving opening in thedrain tube. The gasket may be of suitable material but preferably I usea plastic ring which may be heat sealed to the front wall of the draintube. The stoma 13 enters the opening 12 as noted in FIG. 5. The stomacone 6 is preferably located inside the drain tube and has a flatannular rim 14 which is fixed to the inner side of the rings 23 forlocking the free ends of the belt to hold the drain tube taught on thepatient.

Low cost of the irrigator is further effected by the improved stomacone. To this end I employ low cost aluminum molds to form thin flatsheets of polyethylene or other suitable material, wood, plaster, orplastic into numerous cones. The cones adjoin sufficiently to allow forthe rims 14 to be die cut from the sheet. The cone shapes are formed byconventional vacuum techniques. This low cost is an important factor inmaking the irrigator available as a disposable article.

The stoma cones can also be made by injection molding but the high moldcost can only be justified when the quantity is large enough.

The irrigating function is well known in this field and after completingthe supply of fluid into the stoma the catheter will be removed and thedischarge from the stoma will be into the drain tube.

It will be understood that in the practice of this invention changes maybe made in details and embodiments without departing from the spirit andscope of the invention as expressed in the appended claims, in which Iclaim:

1. An irrigator drain with stoma cone for ostomy patients comprising, incombination with a catheter tube adapted for connection to a source ofliquid supply for the irrigation action, a drain tube having front andrear side walls of flexible film, the front wall having a stomareceivingopening, a cone positioned within the drain tube in alignment with thestoma-receiving opening and with its pointed end adjacent to saidopening, the cone having at its wide end an annular outwardly extendingperipheral wall fixed to the rear film wall of the drain tube andadapted to be grasped by hand from the rear catheter action.

I 2. An irrigator as set forth in claim 1, wherein the cone ispositioned entirely within the drain tube and the annular wall of thecone is fixed to the inner side of the rear film wall of the drain tube,and wherein said rear wall of the drain tube has a relatively small slitopening for passage of the catheter tube into the cone.
